  1. The numbers in parentheses indicate the number of monkeys.
  2. aIndicates numbers of monkeys showing positive results with that method.
  3. bIndicates numbers of positive monkeys compared between the two methods; the left number is for the method used in that column, and the right number is for the method used in that row. For example, by comparing the mIGRA and TST methods in row 1, columns 2 and 3, 14 monkeys had positive results with the mIGRA, but only 8 and 7 monkeys were shown to be positive by the TST and TB culture, respectively.
